IJISPENSIHG: AND DISPLAY PUMP.

Application filed August 28, 1922. Serial No; 584,809.

T o all whom z't may concern.'

Be it known. that we, WILLIAM S. Town-v saNn and FRANK E. DoUGLAss, citizens of the United States, residing at Rochester,

5 in thc county of Beaver and State of Penn Sylvania, have invented certain new and useful Improvements in Dispensing and lDisplayPumps, of which the following is a speciiication.

for oil dispensing pumps, as shown in our application Serial'No. 567,836, tiled June l2., 1922.

The object of the invention is to com- 15- bine a measuring pump with a. visible display means of the character shown in said application. This object is-accomplished by the construction shown in the accompanying drawing. in which:

20 ig. 1 is a central vertical section of our improved dispenser.

' Fig. 2' is a front elevation thereof.

ig. 3 is a side elevation showing an- `other use of the dispenser.

Fig. 4.- shows a modified form of display container.

IFig. 5 is the enlarged vertical section of the upper end of the display cylinder. Fig. 6 shows the central guide tube partly au in section.

Figs. 7, 8 and 9 are detail views of the pump-cylinder head.

Fig. 10 is a detail sectional viewtof the foot piece ot the pump cylinder.

Figs. 1J and 12 show details-of the pumppiston; and Fig. 13 is a plan of the foot piece of the pump cylinder.

Referring to the drawings, the lower or foot piece 1 of the pump cylinder 7 isof 40 a general funnel-like form with a plurality of apertured lugs 2 at intervals around its upper wide end and the head piece 8 of the cylinder is provided around its lower edge with similar spaced lugs 9; the said foot 45 piece 1 andhead piece 8 being connected by the rods 10 which draw them securely together upon the ends of the pump cylinder. r.The lower or foot piece l is provided with an upwardly opening check 30 valve 3, a depending threaded attaching nipple 4 squared at 5 so as to receive a wrench, by means of which the pump may be secured to the spud of a barrel, drum7 stad or other support. 56 epending from the foot piece l just Uur invention relates to display meansl v.turning with the drip back below the valve 3 is the inlet or suction pipe 15 to extend down into the barrel, cask or the like, and this pipe 15 isprovided with a lower section 16 in sliding connection therewith justed for barrels, etc., of varyingfde th. This section 16 'is' provided with a p ain stufling box 17 screwed into the upper end so that 'it may beadso that it may be properly adjusted and held' in its adjustedv position.

The foot piece 1 is further provided with an inclined inlet outer end of which is a drlp pan 19 pro-` vided with a-grid 20-resting on an annular series of lugs 21. A circular Screen 21' i8 also provided so that all dust, grit and other foreign. matter will be prevented from reto the barrel or the like. Gaskets 22 will be provided for the ends of the pump cylinder.

The head piece 8 ofthe pump cylinder 7 is formed as a casting provided with a closed upper end having an annular.seat 23 for the lower end of the inder 2%, and with a threaded aperture 25 opening into the lower end of said display cylinder. .The side of the head'piece 8 has a discharge outlet 261 from which leads the upwardly inclined discharge pipe 27v provided with a-depending outer end directly over` the drip pan-19 and provided with a downwardly opening check valve28; this construction forming. a non-drip outlet or discharge for the pump.

The cap piece 29 forV upper end of the glass display cylinder 24 is provided with a central aperture through which extends pipe or nipple 18 on the glass display cylas. i

the upper threaded end 31 of a tube 30. The

lower end of the tube 30 is screwed into a threaded aperture in the center of the pump cylinder head 8 and receives the upper end of the rack 32 ot'` the pump' piston 33. The

toothed edge of the rack is engaged by a pinion 34, thesliaft in bearings iii-the head 8 vwith its ,outer end extending through a stumng box 36. crank 37 is secured to the outer end of the shaft for rotating the pinion to raise and lower the rack and piston. The plain or rear edge of the piston rack'32 engages guide lugs 38 opposite to the pinion 34 so that the rack cannot be forced out of engagement with the pinion and will be held to travel in a straight line.

' Thepiston 33 is formed of a disk 40 hav- 35 of which 1s mounted ing a central aperture for the lower end oi' the rack and a plurality ofopenings 41. n

top of the disk 40 is a cupfleather 42 hld at its center on the rack and held yieldingly therebeyond over the openings41 by a spring,

43 having a plurality of arms 44. As before stated, the lcentraltube projects through tle cap piece 29 and upon a plug 46 screwed into its threaded end 31 is a' nut whichv forces the cap 29 and the glass cylinder 24' down' towards the pump cylinder 'head 8. Suitable. gaskets 46 are placed at the ends of the glass display cylinder.

The threaded plug 46 hasV a central threaded bore in which is screwed a gage -screw 47 'which'mayjbe' adjusted lso as to limit the upwardrnovement of therack and piston and soy accurately adjust' the amount f of oil lifted bythe piston and discharged 20 through the discharge.v spout.'- Usually the screw 47 `will be set so that the pump will discharge a quart o f oil whenever the piston is moved tothe upward limit. The plug 46 and screw 47 close the' upper; end of the cenanyoil being discharged through the tube 30. This tube30 not only serves as a guide' tube enclosing the .upper end of the rack but is also a central connecting rod to hold the,

display cylinder in place.` The cap piece 29 is provided with' a manually closedy vvent valve 50.

In operationl the pump is secluredin the spud or bung hole of a drum or barrel'with the bottom of the drum or barrel and the 'vent 50 open. The crank is operated in one direction to raise the piston and fill the pump cylinder with oil. `The movement of the' crank will now'be reversed and the oil `will pass upwardlythrough, the piston openings and around the 'cup leather. On the next upstroke ofthe piston, the cup leather will close the piston o enings and lift the oil and ing the same. The air. vent 5() will now be closed and subsequent like operation oiA the pump will cause a measured quantity ot' oil`` to be discharged through the valved outlet spout into any suitable container resting on the s traincr'supported on the drip pan grid'. The outlet valve being self-closing shuts off and( prevents dripping of the oil immedi ately after the -upstroke of the piston has ffbeen completed. TheV exact quantity may be determined by adjusting the screw 47.

This mechanism is designed so that the liquid being dispensed is at all times displayed in the glass container to the prospecin this respect as has the display, attachment vin our pending application before referred to.

y Referring now to Fig'. 3 of the drawing, it

will be seen that the mechanismabove'decoupled to an undergroun .intothe `tube 71. l

tral tube 30 so that there is no possibility ofthe lower end of the suction pipe resting onI placed in position.

force it up into tie display cylinder 24 tillf ydisplay container, and means connecting said cap with'the upper end of said pump cylintive buyer yand it 'has the same .advantages scribed, instead of being secured directly to a barrel or the like may be mounted on a A pedestal or standard comprisinga cap piece 61 havin athreaded aperture for.v the threaded Anipp e 4, a base 62 and a cylind rical body 63 held between ,the cap and base; the suction tube 154-16, extending down through the tube 60 and base 62. The lower end of this `suction ipe coul/d'then be storage tank, not

shown.

In Fig.`4 is shown a further Vmodification with respect to the display container; there,

instead of a sinole glass cylinder as in Fig. l, are provided two parallel glass tubes 7 0-71 connectedwithin thecap piece 72 by a curved passage 73. The lower end of tube opens into the pump cylinder head 8 and the lower end vof the tube 7l opens directly into the discharge nozzle 27, so that as the pump piston rises it will force the oil up glass tube 70 and down through the .The central tube 30 acts to guide and enclose the piston rod or rack and valso to connect'the cap piece 72 and head 8,- and also contains the same plug 46 and adjusting screw 47 for the piston rack.

The tube`3U is provided with athreaded aperture 30 within the display cylinder 24, which is normally open to vent tube 30 and permits proper operation of the-piston rod. Should the display cylinder 24 get broken, i.

however, a plug not shown will be screwed in to close the aperture and the aperture 25 in head 8 vwill also be closed bya suitable plug not shown, whereupon the pump may ,be operated without the display feature until another display cylinder` 2l may be Various changes may be made without depart-ing from the spirit of my invention.v In

Fig. 3 it will be noticed that the drip from pan 19 will flow into the cylinder 60 from which it may be withdrawn by a spigot 64.
